I may be wrong on the contamination issue. The real issue is that I
do not have permission to download anything but Apache licensed code.

Exactly. Harmony won't bundle non-Apache code with its download. The
goal is a complete Apache licensed JVM stack that works right out of
the box. This includes a GC. If Harmony modularization is
successful, third parties can plug in non-Apache components such as a
GC from Jikes, Rotor, Sun, etc.

Unfortunately, I am not allowed to proceed until the license issues
are worked out.
